We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of preeminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war.

Let us not be blind to our differences-but let us also direct attention to our common interests and to the means by which those differences can be resolved. And if we cannot end our differences, at least we can help make the world safe for diversity. For, in the final analysis, our most common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.

The war against hunger is truly mankind's war of liberation.

So let us here resolve that Dag Hammarskjold did not live, or die, in vain. Let us call a truce to terror. Let us invoke the blessings of peace. And, as we build an international capacity to keep peace, let us join in dismantling the national capacity to wage war.

I believe in an America where the rights that I have described are enjoyed by all, regardless of their race or their creed or their national origin - where every citizen is free to think and speak as he pleases and write and worship as he pleases - and where every citizen is free to vote as he pleases, without instructions from anyone, his employer, the union leader or his clergyman.

Now the trumpet summons us again - not as a call to bear arms, though arms we need; not as a call to battle, though embattled we are; but a call to bear the burden of a long twilight struggle, year in and year out, 'rejoicing in hope, patient in tribulation', a struggle against the common enemies of man: tyranny, poverty, disease and war itself.

While we cannot guarantee that we shall one day be first, we can guarantee that any failure to make this effort will make us last.
